Naval engineering standard 713 toxic index analysis chamber, Toxicity Index Test Chamber, NES 713
This tester measures the Toxicity Index by ppm in Neval Engineering Standard chamber when complete combustion occurs by burner.
FESTEC's NES 713 TOXIC Chamber meets the standard of NES 713 and is used to measure combustion characteristics about materials.
NES 713 Toxic Chamber measures Toxicity Index after perfect combustion by burning 100g of specimen.

  • Methane Gas & Cylinder, 2 Stage Regulator
• Observation window made in reinforced plastic allows easy observation of combustion conditions during the test.
• Chemical reaction with gaseous materials generated in combustion is minimized by treating the inside of Chamber with Teflon Coating.
• Door locking device designed for easy opening/closing
• Specimen Support for Burner to be located in the center of the combustion mass and for test specimen to be easily loaded
• Designed for testing in Auto/Manual Mode
• Auto Ignition for controlling ignition and extinguishment of Gas Burner by Time Device
• Auto Vent Mode allowing auto release of combustion gases generated in combustion by Time Device
• Auto Stirrer Mode for complying with conditions of combustion gas stirrer by Time Device specified in the standard Time Device
If 100g of material is burned and the material is diluted in the air of chamber, concentration of each generated gas is given by the following equation.
         C ¡¿ 100 ¡¿V
C8 = --------------- (ppm)
                 m
C = concentration of gas in test chamber (ppm)
m = fire test mass (g)
V = volume of test chamber (m3)

Toxicity Index
                             C81     C82      C83                C8n
Toxicity Index = ¥Ò ------ + ------ + ------ + ¡¦ + ------
                              Cf1     Cf2      Cf3                  Cfn
1, 2, 3, ... indicates each found Gas.
Cf = concentration of the gas considered fatal to man for a 30 minute exposure time(ppm)
